Methylene Chloride (DCM) Survey

Methylene Chloride (DCM) Survey

Environmental Health and Safety (EHS) is conducting a survey to understand how methylene chloride (dichloromethane/DCM) is used in our laboratories and to prepare for upcoming regulatory changes set by the EPA. These new regulations focus on stricter exposure limits, enhanced safety practices, and improved training requirements to reduce health risks associated with DCM. Your input is vital in helping us assess current practices, identify challenges, and ensure compliance while maintaining a safe and efficient work environment.

Acknowledgement*

I acknowledge that I have reviewed the EPA’s upcoming regulatory requirements for dichloromethane (DCM) usage and understand my responsibilities as a laboratory supervisor. To ensure compliance with these regulations, I will implement the following workplace requirements:

Develop and Implement a Workplace Chemical Protection Program (WCPP):

Establish a documented program outlining procedures for minimizing DCM exposure, including engineering controls, administrative controls, and personal protective equipment (PPE).

Conduct Exposure Monitoring:

Perform initial exposure monitoring by May 5, 2025, for existing facilities, and within 30 days of starting DCM use in new facilities. Periodic exposure monitoring will be conducted every five years or as required.

Maintain Exposure Levels:

Ensure that DCM concentrations in the lab do not exceed the EPA's Occupational Exposure Limits (OELs):

2 ppm as an 8-hour time-weighted average (TWA).

16 ppm as a 15-minute Short-Term Exposure Limit (STEL).

Develop an Exposure Control Plan:

Implement a comprehensive control plan by October 30, 2025, including ventilation systems, administrative protocols, and PPE usage.

Provide Appropriate PPE:

Supply lab personnel with PPE, such as chemical-resistant gloves and respiratory protection, when exposure control measures are insufficient.

Conduct Training:

Ensure all personnel handling DCM complete training on safe handling practices, potential health risks, and emergency response procedures before working with the chemical and through periodic refreshers.

Maintain Records:

Keep detailed records of DCM usage, exposure monitoring results, training sessions, and any incidents or spills involving DCM.

Notify Personnel:

Inform lab personnel of exposure monitoring results and any incidents promptly and ensure they understand how to access resources and support.

Financial Responsibility:

I understand that my department is financially responsible for all required monitoring, equipment, and compliance measures, including exposure assessments, ventilation upgrades, PPE procurement, and any other necessary expenditures.
